Re: m100Hd - AE

In your Applications folder>Media 100 HD folder you should see a folder called Adobe After Effects Plug-in. In it, you should see a plug-in called Media 100 XML Project Importer. If you Get Info on this plug-in, there is a "Open with:" arrow, and when click on it, it should reveal (confirm) what version of After Effects you have, which will open the XML file.

I just drag the XML file from my desktop onto the AE application icon in the Dock, and this always works for me. I'm only using AE 6.0, but it works fine.
